Forecast discussion: High pressure over the Great Lakes Sunday night moved over eastern Canada earlier on Monday. This helped keep a low pressure system over the Mid-Atlantic south of New England. We missed seeing any snow showers, although the south coast did receive some flurries. As we head into the week, spring will arrive officially on Thursday. But, by the weekend, winter will make a grand return.

High temperature forecast for March 18, 2014

The high will bring clear skies and calm winds for tonight, making temperatures fall to the middle teens. This is well below normal for the middle of March. Northeast winds will keep our temperatures in the upper 30’s for Tuesday, but overnight lows for early Wednesday morning will be in the lower 20’s.

We will begin Wednesday with sunshine, but the high’s center will begin to move offshore. A low pressure system moving across eastern Canada will provide us with some showers by Wednesday evening. There will be enough warm air in the atmosphere to keep it as rain showers into the middle of Thursday morning. We will have spring arrive by 12:57 p.m. It will also be the warmest day of the week, as highs climb into the lower 50’s.

By Friday, a new cold front will bring some colder air from Canada back into New England. It will be cold enough for the precipitation to be snow showers before midnight on Friday. By the time we reach the middle of Saturday morning, it will change to rain showers, and remain this way until it ends Saturday evening. After the cold front passes, Arctic air will rush back over the region, and our high temperatures will be well below normal. We will see partly to mostly sunny skies for the start of next week, but temperatures will make it feel more like January than the last full week of March.
